Has anyone run a B&M 144 Supercharger on a mostly stock 302?

I’ve found a pretty good deal on one and may pick it up this weekend.

Started on my rearend build last night.
This is a stock 273 gear rearend I’ve had in my stash for a while.

Someone broke off the cross pin bolt and left it but I got it apart with an extractor.

Still wavering between 410 and 373. I have both gear sets on hand.
This will be a track rearend, I’ll keep the 355 rearend so I can swap back if I change what I use the car for.

Great news, our local track is open!
No spectators allowed, only driver and crew, and physical distancing enforced.

My dad wants to get out of the house so he may be my pit crew Friday night.

My rearend build stalled out because of lockdown so it looks like I’ll be keeping the 355 gears this season.

Wow the car ran great today.
So upgrades from last year are:
Line lock
Slicks
Front runners
Hurst shifter

Track prep was bad and this was the first weekend that the track was open so 1/8 mile only.

Car ran a best time of 8.72 @78mph

Very happy overall!

My competition is almost ready.
My dad has a MK3.1, same engine and gears as my car but his has an AOD.
We’re planning to race at the CK nationals in August, probably in the street car class which requires street tires so we will likely even be running the same rubber.

I’ve added a drive shaft loop and yesterday received current dated harnesses so dads car is almost ready to race!

Planning to go to test and tune this weekend,
Since I had the car jacked up to put the racing tires on I moved the upper control arm bolt to the lowest hole. I had some axle hop in the middle hole.

I Dropped air pressure and shifted harder on run 2 and I picked up a lot!
13.41 at 100.14 mph! A personal best.

This weekend I participated in my first competition race.
Ran an 8.41 1/8 and broke out and was eliminated in the first round, but I had a great time!

This weekend at the track was not what I’d hoped for.

We went to St Thomas Dragway for the Hotrod Reunion Friday to Sunday.
Friday night was test and tune and then points racing Saturday.

On my first run Friday night the car in the other lane was ahead of me when it came apart and I picked up what I think is a piece of bell-housing in my radiator.
FFR 5886 was out of commission for the weekend after one Friday test and tune pass. At least I’ve got all winter to replace the radiator.

My dad brought his cobra and let me make some passes Saturday. All my friends ran great and made it to the finals, then we set up the movie projector and watched Cannonball Run.

I made a prototype grill out of foam board to see how it would look and work out the dimensions.
I like it enough that I’m going to make one out of aluminium.

I ran one on a stock 5.0 in a '85 mustang back in 92, 6 psi boost, 9" Rear w/ 3:90 gears, and Slicks, went 12:95 in the 1/4. Daily driver, never had any problems.

New Radiator is here.
This is the American Eagle 2 row 1”tube all aluminum from champion.
Looks pretty good.

New radiator is sitting in place.
Of course the mounting flanges are 1/2” off so I had to re drill some holes.
I also made a lower rad mount to support the new much more expensive radiator. I had used the FFR method of holding the bottom of the rad with just the aluminum, but I never liked that.

I also was never quite happy with how the wiring for the headlights was routed. The harness passed along the bottom of the rad so I disconnected it all to get it out of the way of removing the old rad. Tonight I’ll finish the rad install and then work on cleaner wire routing.

And I’m finally doing a 3G alternator upgrade. When I first built the car I retained the 2g alternator because my donor came with a brand new alternator, probably the only part on the donor that didn’t get replaced or rebuilt.
The 2g worked fine for driving around, but sitting in the staging lanes with the car at idle and the electric fan running it couldn’t keep up. The 2g barely charges below 1200rpm.
Fortunately I found a 3G on Amazon Warehouse deals for $24! It said cosmetic damage but I can’t see anything wrong with it.

One of my friends posted a video of the run where my rad got taken out.

The cobra is all back together, no leaks!
Unfortunately I noticed today that the tailpipe is falling off my truck so I’ll have to fix that before towing the car to the track next weekend.

At lest the Covid is keeping me from having to visit my mother in law for thanksgiving this weekend.
I told my wife if it’s not one thing it’s your mother!

We had a great test and tune day Saturday!
It rained in the morning so very few cars showed up, I got 5 runs in and could have done more but some friends I haven’t seen in a month were there and we spent a little time catching up.

The car ran great but I had slow times. They only ran 1/8 mile.
It was cold so I dropped air pressure looking for traction.
That was a mistake, the car felt loose at higher speeds so I kept backing out of the throttle in 3rd gear.
I did figure out how to do a better burnout and launch. I need to really stomp on the brake when I set the line lock, and a little spin in the water box to wet the tires all the way around makes a huge difference.
My 1/8 times sucked at 9.50’s but my reaction and 60’ times are improving.

That’s it for the season, 5 trips to the track this year.
Looking forward to next year!

I’m back to working on the cobra.
Lockdown continues for us so it’s nice to have a warm well appointed garage to retreat to at the end of a long day or working from home and helping kids with virtual school.

I’m tidying up a few things on the car this winter.
I scraped the oil pan and the drain plug doesn’t seal, but I have a spare new pan in stock so I’ll replace that.
I’m also changing some switches and buttons on the dash for looks.

The car felt like the brakes were dragging so I pulled the calipers off, the pistons seem to be moving fine but the slider pins were dry. I lubed them with sylglide but it may need new rubber bushings.

I’ve made a mess,


I bottomed out the car and dented the oil pan, to get by I siliconed the drain plug in.
I had a nos ford oil pan in my parts stash so I figured this winter was a good time to swap in.

While under the car i noticed some oil on the bellhousing.

Turns out it’s leaking oil from the flywheel bolts.
I don’t remember what I used on the bolts but it didn’t keep all the oil inside.

Good news is my clutch isn’t oiled down.
It still looks like new so I’m at least as good a driver as I am a mechanic lol.
